Hi all! I’m looking to create an entertainment system for my treadmill, which I will use two handheld remotes to act as a wireless controller connected to a raspberry pi, to play games as I run. Each controller will have a joystick and a few buttons, along with an Arduino (Nano Pro 3.3v) and RFM69 (although I’m open to other suggestions if thats not the best transceiver to use). The wireless signal will then be picked up by an Arduino Leonardo and act as a keyboard/mouse input to the Pi.
I’ve never used a RFM69, however, so want to know how I could connect it 3 way (so that the two controllers are transmitting to the same Arduino). Do I need to purchase two sets of transceivers, or is it possible for one transceiver to receive two signals? Also if I did do two sets, should I purchase different frequencies? Alternatively could one controller to transmit to the other, and then that one to send both signals to the receiver? I should also note I’m not expecting to need to transmit any info from the Leonardo back to the controllers, so it will just use a one way signal.
Thanks for the help!
Edit: Upon some more research I’ve found the RF Link Transmitter and Receiver, however Sparkfun looks to be out of the 315 MHz receiver. Is it possible to use two transmitters to be picked up by one receiver, and is this a better choice than the RFM69?
